Abstract (en)
An adjusting device for phase shifter of antenna in mobile communication includes a gear, a rack, a screw, a driving nut, a driving shaft and a manipulating member. The gear is fixed to a rotation axis of a phase shifter on a reflecting plate of the antenna. The rack is fixed to the driving shaft. One end of the driving nut is fixed to the driving shaft. The other end of the driving nut is provided with an internal screw hole engaging with the screw. The manipulating member is jointed to the screw at one end thereof. The driving shaft and the screw are respectively supported by a driving shaft supporter and a screw supporter on the reflecting plate of the antenna. A control device is coupled to the adjusting device. The control device is formed with a rotation shaft to be suitably received in the slot in the head of the manipulating member. The present invention need not modify internal structure of the control device for different mechanical route of the phase shifter. Thus, the adjusting device according to the present invention has an approved universality and can adjust the electrical down-tilt angle more precisely.
